All My Sons introduces themes that thread throughout Arthur Miller's work: the relationships between fathers and sons and the conflict between business and personal ethics. In this classic American drama, Joe Keller and Steve Deever, partners in a manufacturing plant during World War II, turned out defective airplane parts, causing the deaths of many men. They were sent to prison, but Keller was exonerated and went on to have a successful business. In a work of tremendous power, a love affair between Keller's son and Deever's daughter, the bitterness of George Deever and the reaction of a son to his father's guilt escalate toward a climax of electrifying intensity.
